    In KALDI, Can I specify an utterance and run MLLR using an existing model, forcing all utterances in a training-data set to align to the utterance I specify and outputting a likelihood (or some probabilistic measure) that each utterance is a match to the utterance specified? [Some call this 'forced alignment'].

    I have looked into the steps/align_*.sh scripts and am not sure if they are where I should be looking. Thanks ^_^

      I think you may not understand what MLLR is.
      You could do what you say by creating a data directory where you
      replace all the "text" files with a given utterance, but even if you
      created the likelihoods (I think it may be an optional output of
      gmm-align-compiled) it wouldn't give you very meaningful measure at
      all. Better to run data/cleanup/find_bad_utts.sh which I think gives
      more meaningful diagnostics of whether an utterance's transcription is
      correct.
